JUSTUS A. GUSTAFSON, OF IDAHO SPRINGS, COLORADO;

MINERS ACETYLENEGAS LAMP.

Specification of Letters Patent.

Patented June 8, 1915.

Application filed. August 29, 1914. Serial No. 859,259.

To all whom it may concern:

Be it known that I, JUsTUs A. GUSTAF- SON, citizen of the United States,residing at Idaho Springs, in the county of Clear Creek and State ofColorado, have invented panying and forming part of this specifica-,

tion, in which:

Figure 1 is a side elevation showing my novel lamp in readiness for use,and also showing by dotted lines the position to which the bail is swungto bring about disengagement of the links from the projections on thegenerating tank. Fig. 2 is a detail vertical, diametrical section takenin a plane parallel to Fig. 1. Fig. 3 is a detail view, partly inelevation and partly in section, showing the manner in which theadjustable sleeve on the bail cooperates with the upright on the coverto look the cover on the generating tank.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings.

The generating tank 1 of my novel lamp is provided interiorly with aforaminous tube 2, which is removably held in position by a spring 3,fixed to and rising from the bottom of the tank. At its upper edge saidtank is preferably flanged as indicated by 1, and exteriorly it isprovided with the conventional hook 5 and a burner tube 6, equipped withan apertured tube 7 By preference the tube 6 is charged with cotton 8designed to remove impurities from the gas precedent to the consumptionthereof.

Removably arranged in the tank 1 is a combined cover and waterreceptacle 9. Said receptacle is provided with a normally closed fillingaperture 10 and an exterior flange 11, and at the underside of thelatter is a gasket 12, designed and adapted to hermetically seal thetank 1. In its bottom the receptacle 9 is provided with a dischargeaperture 13 surrounded by a depending tube 14, snugly occupied by a wick15 which has for its purpose to retard theflow of water into the tube 2and from thence into the tank 1. Fixed to the cover or combined coverand upright and arranged adjacent the edge thereof is an upright 16.Pivoted at diametrically opposite points to the upper part of the waterreceptacle and cover is a bail 17, on which is pivoted the usual prong18, and adjustable vertically on one side portion of the said bail is asleeve 19;

Pivotally connected at 20 to the end portions of the bail l7 and off thecenter of movement of said bail are links 21. These links 21 haveinclined notches 22, designed to receive lateral and headed projections23 on the tank 1; the said projections 23 being preferably inclined asshown with a view to facilitating engagement of the notched'linksthereto.

y In the practical use of my novel lamp, the tank 1 is charged withcalcium carbid, and the combined cover and recep-- tacle 9 is filled tothe extent desired with water. The receptacle is then placed in the tankwith the parts relatively arranged as shown inFig. 1, after which thelinks are swung into engagement with the projections 23, and the bail 17is arranged in. vertical alinement with the links, and the sleeve 19 isadjusted down so as to SUI'I'OUlld. the

upright 16. With this done the combined cover and receptacle 9 will behermetically sealed on the tank 1 to prevent the escape of gas from thelatter except through the tip 7. It will also be noted that the gasket12 will be compressed against the tank, and that bined cover andreceptacle being released from the tank 1. When however, it is dethereis absolutely noliability of the oomsired to remove the combined coverand receptacle, the same can be expeditiously and easily effected afterthe sleeve 19 is moved upwardly'olf the upright 16, and the bail 17 andlinks 21 are swung to the positions shown by dotted lines in Fig. 1.

Having described my invention, what I claim and desire to secure byLetters-Patent, 1s:

1. In means for the purpose described, the combination with a tank, of acover removably arranged on the tank, an upright fixed to the cover, abail pivoted to the cover, an adjustable sleeve movable on the bail andon and off said upright, and cooperating means on the tank and the bailfor locking the cover on the tank When the bail is secured by the sleeveto the upright.

2. In means for the purpose described, the combination of a tank havinglateral projections, a cover removably arranged on the tank and havingan upright, a bail pivotally connected to the cover, a sleeve adjustableon the bail and on and off the upright, and links pivotally connected tothe bail and notched for engagement With the projections 10 of the tank.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Wit Copies oi this patent may be obtained for five centseach, by addressing the Commissioner of Patents,

Washington, D. C.
